'Linking Starbursts, Major Mergers, and Absorbed AGNs at Redshift~0.7'

I will present a detailed study of the occurrence of star formation,
active galactic nuclei (AGNs), and galaxy mergers in a sample of
70-micron selected galaxies from the Far-Infrared Deep Extragalactic
Legacy survey (FIDEL). Deep multiwavelength observations reveal a
complex connection between starburst, AGN, dust obscuration, and gas
outflows.

We find a higher AGN fraction in 70-micron selected galaxies compared
to previous studies. This difference may be due to 70-micron
galaxies hosting AGNs that are heavily absorbed (Compton-thick). I
present evidence that these systems are ideal test-beds for merger
scenarios in which gas-rich galaxies merge, go through a
deeply-embedded ULIRG phase before emerging as an X-ray and optically
identified AGN. I compile galaxies at different evolutionary stages
allowing us to witness this process at redshift ~ 0.7. Lastly, I will
highlight the potential of future multi-wavelength studies to
constrain such evolutionary scenarios.
